How does 1015 Chestnut Street compare with other office buildings in Philadelphia?
The latest disclosures cover 212 office buildings in Philadelphia, out of 2,379 buildings citywide. 1015 Chestnut Street's ENERGY STAR score of 77 compares with an average of 64 across the 180 that report a score; it scores higher than 67% of them and lower than 29%. Its site EUI of 48.6 kBtu/ft² is about 38% below the average of 78.3 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 135,000 sq ft, it is about half of the average floor area of 292,223 sq ft for those buildings. It was built in 1940, 17 years earlier than the group's average year built (1957). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
What does an ENERGY STAR score of 77 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 77 means the building performs better than about 77% of its national peers. BuildingCensus bands the score into report-card grades; 77 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In Philadelphia, 35% of scored buildings are at 75 or above.
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. 1015 Chestnut Street's 48.6 kBtu/ft² across 135,000 sq ft works out to about 6.6 billion Btu (1,923 MWh-equivalent) in 2019. Its source EUI of 128.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,733,193 kWh of electricity and 183 thousand gallons of water for the year.
Which law requires 1015 Chestnut Street to report its energy use?
1015 Chestnut Street reports under Phila.
